Ukuthelekisa iqokobhe{0}}kunye{1}}netyhubhu kunye nomoya{2}}izitshintshi zobushushu ezipholileyo

1. Ubume kunye noMgaqo weqokobhe{1}}kunye{2}}neziTshintshiselwano zoBubushushu beTube

Iqokobhe -kunye{1}}netyhubhu yokutshintshiselana ngobushushu ngamanzi{2}}izixhobo zokutshintshiselana kobushushu obupholileyo. Ulwakhiwo lwazo olungundoqo lubandakanya iqokobhe lentsimbi, iinyanda zetyhubhu zangaphakathi, amaphepha etyhubhu, kunye neminqwazi yokuphela, okukhokelela kulwakhiwo oluqinileyo kunye{4}}olulungelelanisiweyo. Umgaqo osebenzayo ubandakanya ukutshintshiselana kobushushu phakathi kwee-fluids ezimbini: enye igeleza ngaphakathi kwi-tube bundle, ngelixa enye ihamba kwi-gap phakathi kwegobolondo kunye ne-tube bundle. Amanzi yeyona ndlela yokupholisa, kwaye utshintshiselwano lobushushu luphunyezwa ngeendonga zetyhubhu. Iindidi zolwakhiwo eziqhelekileyo ziquka uhlobo lweshiti ityhubhu esisigxina, uhlobo lwentloko edadayo, kunye nohlobo lweU{8}} lombhobho.

2. Ubume kunye noMgaqo woMoya{1}}IziTshintshisi zoBubushushu obupholileyo

Umoya-izitshintshi zobushushu ezipholileyo zisenziwa ikakhulu ziityhubhu zentsimbi, amaphiko ealuminiyam, iifeni zokuhamba kweaxial, kunye nezakhelo. Abafuni manzi okupholisa; endaweni yoko, i-fan iqhubela umoya we-ambient ukuba itshayele ngaphaya kwee-bundles zetyhubhu ezifihliweyo, kwaye umjikelo wotshintshiselwano lobushushu ugqityezelwa yi-airconvection ethwele ubushushu obusuka kulwelo. Isakhiwo esipheleleyo sikhaphukhaphu kwaye asinazo iinqununu zesekethe yamanzi.

1. Ukusebenza kunye nozinzo lweqokobhe{1}}kunye{2}}nezitshintshi zobushushu ityhubhu

Iqhayisa ngokusebenza okuphezulu kunye nokuzinza ngakumbi kokutshintshiselana kobushushu. I-thermal conductivity yamanzi iphezulu kakhulu kunomoya, nto leyo ekhokelela kumahluko omncinci wobushushu, utshintshiselwano lobushushu olusebenzayo, kunye nokuchaneka kokulawula ubushushu obuphezulu. Isixhobo siyakwazi ukulungelelaniswa nobushushu obuqhubekayo kunye nokusebenza okuzinzile, okungathintekiyo ngokuguquguquka okuncinci kwiqondo lokushisa eliphakathi. Nangexesha-lokusebenza okuqhubekayo kwexesha elide, ukusebenza kakuhle kotshintshiselwano ngobushushu kuya kubola kancinane, kuyenze ifanelekele{4}}ukuchaneka okuphezulu, okuphezulu{5}} komthwalo oqhubekayo weemeko zemveliso. Iyakwazi ukwamkela ukutshintshwa kobushushu kwisigaba (i-condensation, vaporization) ukuhlangabezana neemfuno zokutshintsha ubushushu.

2. Ukusebenza kakuhle kunye nokuzinza komoya{1}}ubushushu obupholileyo

Ukutshintshiselana kobushushu kuncinci, kwaye umoya une-conductivity ephantsi ye-thermal. Ngaphantsi kweemeko ezifanayo zokusebenza, ukusebenza kakuhle kokutshintshisana kobushushu yi-15% -20% ephantsi kunohlobo lwegobolondo kunye netyhubhu. Ukuzinza kokusebenza kuchaphazeleka kakhulu kubushushu be-ambient. Amaqondo obushushu aphezulu ehlotyeni aya kubangela ukunyuka kweqondo lobushushu kunye nefuthe lokutshintshiselana kobushushu liyancipha, kunyanzelise ukwanda komthwalo wezixhobo. Amaqondo obushushu aphantsi ebusika, imvula, ikhephu, kunye nemozulu enothuli nazo ziyakuchaphazela kancinane ukuzinza kotshintshiselwano lobushushu. Ukuchaneka kokulawula ubushushu kubanzi.

1. Ukuziqhelanisa neqokobhe{1}}kunye{2}}nezitshintshi zobushushu ityhubhu kwiimeko ezahlukeneyo zokusebenza

Ilungele iimeko zamashishini ezirhabaxa, inoxinzelelo olubalaseleyo kunye nokumelana nobushushu obuphezulu, ekwaziyo ukumelana namaqondo obushushu ukuya kuthi ga kwi-400℃kunye noxinzelelo ukuya kuthi ga kwi-10MPa, iyenza ifanelekele{2}}uxinzelelo oluphezulu kunye{3}}imeko yemveliso yobushushu ephezulu kwipetroleum, imichiza, kunye namashishini anzima. Ityhubhu inyanda inomnqamlezo omkhulu -icandelo, iyenza ukuba ingavaleki kakhulu. Iyakwazi ukulungelelaniswa nolwelo oludlekayo kunye ne-viscous ngokutshintsha izinto ezifana nentsimbi engatyiwa kunye ne-titanium, ebonisa ukuqina olomeleleyo kunye nokuhlangabezana neemfuno zokutshintshiselana kobushushu kumajelo osasazo ahlukeneyo oshishino.

2. Ukuqhelaniswa komoya{1}}nobushushu obupholileyo bokutshintshisa kwiimeko ezahlukeneyo zokusebenza

Ifanelekile kwiqondo lokushisa eliqhelekileyo kunye neemeko zokusebenza zoxinzelelo oluphantsi, kodwa ayikwazi ukumelana noxinzelelo oluphezulu kunye nokusebenza okuphezulu kweqondo lokushisa; ilungele kuphela{0}}uxinzelelo oluphantsi lotshintshiselwano lobushushu. Ifuna ukucoceka okuphezulu kwendawo; i-viscous, ukungcola{2}}okutyebileyo, okanye imidiya eyingozi kakhulu inokubangela ukuvaleka kwee-fin kunye nomonakalo wokutya. Olona ncedo lwayo kukuziqhelanisa neendawo zonikezelo lwamanzi{4}}ezinqabileyo, ezikude, nezingaxhaswanga, nto leyo eyenza ukuba ingathintelwa bubutyebi bamanzi kwaye inika ubhetyebhetye olukhulu ekuziqhelaniseni nokusingqongileyo.

1. Ufakelo kunye neemfuno zesithuba somgangatho weqokobhe{1}}kunye{2}}nezitshintshi zobushushu ityhubhu

Ithatha indawo encinci kwaye inoyilo oludibeneyo. Inokufakwa kuzo zombini izilungiso ezithe nkqo nezithe tyaba ukuze zihambelane neendawo ezincinci zokusebenzela. Nangona kunjalo, ineemfuno zofakelo eziphezulu. Isixokelelwano esipheleleyo samanzi okupholisa kufuneka sakhiwe, kubandakanywa inqaba yokupholisa, impompo yamanzi ajikelezayo, imibhobho yamanzi, iivalvu, izixhobo zokucocwa kwamanzi, njl.

2. Ufakelo kunye neemfuno zesithuba somgangatho womoya{1}}ubushushu obupholileyo

Akukho nkqubo yamanzi ifunekayo; ifuna kuphela unikezelo lwamandla ukuze isebenze. Inkqubo yofakelo ilula kwaye ixesha lokwakha lifutshane, iyenza ifaneleke ngaphandle, -umoya, kunye neziza zokwakha ezikude. Ukungalungi kukuba izixhobo zikhulu ngobukhulu kwaye zithatha indawo enkulu, zifuna indawo eyaneleyo yokungena umoya ukuze kuqinisekiswe ukuhanjiswa komoya. Ayinakufakwa okanye isetyenziswe kwiindawo ezivaliweyo zangaphakathi.
